Does thermoluminescence dating mean
However, it’s well known among radiation physicists that RDRs vary with location, season, solar activity, and even time of day.
Thermoluminescence Dating Thermoluminescence can be used to date materials containing crystalline minerals to a specific heating event.
They divide this by an assumed radiation dose rate (RDR) to estimate the pottery’s age.
At this point, the method seems to be a straightforward concept.
Another problem with the TMRD is the calibration of the detector, since different crystals in an artifact can contain different amounts and/or types of luminescence material.
It is an absolute dating method, and does not depend on comparison with similar objects (as does obsidian hydration dating, for example).The major source of error in establishing dates from thermoluminescence is a consequence of inaccurate measurements of the radiation acting on a specimen.Luminescence dating (including thermoluminescence and optically stimulated luminescence) is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past.An input of energy, such as heat, is required to free these trapped electrons.The accumulation of trapped electrons, and the gaps left behind in the spaces they vacated, occurs at a measurable rate proportional to the radiation received from a specimen’s immediate environment.
